Young auto flower problems

I’m having some issues with my autos.

Watered yesterday with 6.5 ph dechlorinated water. Woke up to some looking like this.

Only thing that has changed other then watering is I changed the light from a 8 bulb T5 to a 250watt LED. The light is hanging at 24” from the top of the plant.

Other plants in the pics are perfectly fine reaching up toward the light.

Any input is greatly appreciated

You may raise the LED to 36+ inches for the next 7-14 days while your plants adjust. That LED is much stronger than the t5s, the plants will need to adjust. Outside of the one plant drooping, they look ok. The droopiness of the one plant looks much like an issue with either overwatering or underwatering, there are various ways such as guaging how much the pot weighs after watering, and waiting for it to feel light again before watering, sticking your finger into the soil up to your first knuckle, etc. Maybe someone more versed in soil growing can chime in on the watering issue, but that droopiness looks very much water related or root stress related!

Ok I will lay off watering and raise the light
Thanks for your help!

Just wanted to touch base with ya and see if your babies' conditions have further deteriorated or improved. Best of luck hope all is going well.

They are most definitely showing better signs they haven’t been watered since last post and moved to the lights to 36’ away from the top of the plants at the time of the last post.

I will say I also started to give them 4 hours of lights off time. I honestly can say Ive noticed that they start to droop after 18-20 hours. It could all be in my head but I sure do thing it’s doing something.

Even noticed my runt is finally growing (top left in group pic)

some are showing potassium deficiency, ( yellow edges ) .

I top fed them a 2-8-4 10 days ago those edges showed up when I switched lights.

Just figured it was light burn from how strong the new leds are.

Still believe it’s a potassium def? If so how do you recommend to fix it?
